Owing to wearing and unpredictable damage, the working lifetime of triboelectric nanogenerators (TENGs) is largely limited. In this work, we prepared a single-electrode multifunctional TENG (MF-TENG) that exhibits fast self-healing, human health monitoring capability, photothermal properties. The device consists thin self-healing poly(vinyl alcohol)-based hydrogel sandwiched between two silicone elastomer films. MF-TENG short-circuit current, transfer charge, open-circuit voltage 7.98 μA,...
Reducing the swelling of tissue-adhesive hydrogels is crucial for maintaining stable tissue adhesion and inhibiting inflammation. However, reported strategies reducing always result in a simultaneous decrease adhesive strength hydrogel. Furthermore, once covalent bonds break currently hydrogels, they cannot be rebuilt, hydrogel loses its ability. In this work, nonswelling (named as "PAACP") possessing regenerable high synthesized by copolymerizing crosslinking poly(vinyl butyral) with...
Abstract Wearable sensing technologies have witnessed rapid development in recent years due to their accessibility, functionality, and affordability. However, heat accumulation electromagnetic interference electronic components adversely affect the performance seriously damage human health. Herein, cellulose nanofibers (CNFs)‐based composites with high thermal conductivity (TC) excellent (EMI) shielding are prepared using CNFs as templates followed by coating tannic acid non‐covalent...
Flexible piezoresistive tactile sensors are widely used in wearable electronic devices because of their ability to detect mechanical stimuli. However, achieving high sensitivity and low hysteresis over a broad detection range remains challenge with current sensors. To address these obstacles, we designed elastomeric micropyramid arrays different heights redistribute the strain on electrode. Furthermore, mixed single-walled carbon nanotubes micropyramids compensate for conductivity loss...
Abstract A self‐powered and sustainable traffic monitoring system is highly required for future urban development. Herein, self‐healable piezoresistive sensors triboelectric nanogenerators (TENGs) are constructed by in situ polymerization of polyvinyl alcohol‐polyacrylamide double network hydrogel the presence sodium alginate tannic acid‐modified cellulose nanocrystals (denoted as PPC) all‐weather intelligent applications. Because hydrogen bonding boron ester bonding, resultant PPC‐based...
Abstract Wettability significantly influences various surface interactions and applications at the liquid–solid interface. However, understanding is complicated by intricate charge exchange occurring through contact electrification (CE) during this process. The of influence triboelectric on wettability remains challenging, especially due to complexities involved in concurrently measuring angles interfacial electrical signals. Here, relationship investigated between density change angle...
To obtain a dielectric elastomer with excellent properties and actuated strain, we used bio-inspired dopamine to functionalize the surface of barium titanate (BT) particles. X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission (TEM) were confirm that poly(dopamine) (PDA) layer ca. 3.0 nm had been successfully deposited on With introduction PDA layer, compatibility between filler matrix (hydrogenated nitrile-butadiene rubber) was significantly improved,...
